White Light Emission of Bi2O3-B2O3-P2O5 Glasses Doped with Dy3+ Ion

Bismuth borophosphate glasses (Bi2O3-B2O3-P2O5) doped with different concentrations of Dy3+ ion were prepared by meltquenching technique. The structural of the glass samples were characterized through the molar volume. The optical and luminescence properties were studied by investigating absorption and emission spectra of the glass samples. The absorption spectra were carried out in the Vis-NIR regions from 400 to 2000 nm. The emission spectra consists of four emission bands in the visible region that corresponds to the F-4(9/2)-> H-6(J) (J = 15/2, 13/ 2, 11/2 and 9/2) transitions of Dy3+ ion under 453 nm excitation wavelength. Judd-Ofelt analysis exhibits an interesting potential for using glass as laser medium with 575 nm emitting. Calculated chromaticity co-ordinates also confirm its application potential in generation of white light devices. (C) 2018 Elsevier Ltd. All rights reserved.
